Brian,

I don't think that's going to work.  Browsing the include files, I see that
TIOCGFLAGS is used to access the following flags:

#define         TIOCFLAG_SOFTCAR        0x01    /* ignore hardware carrier */
#define         TIOCFLAG_CLOCAL         0x02    /* set clocal on open */
#define         TIOCFLAG_CRTSCTS        0x04    /* set crtscts on open */
#define         TIOCFLAG_MDMBUF         0x08    /* set mdmbuf on open */
#define         TIOCFLAG_CDTRCTS        0x10    /* set cdtrcts on open */

while TIOCMGET is used to obtain the following flags, which use some of the
same bit positions but stand for completely different things:

#define         TIOCM_LE        0001            /* line enable */
#define         TIOCM_DTR       0002            /* data terminal ready */
#define         TIOCM_RTS       0004            /* request to send */
#define         TIOCM_ST        0010            /* secondary transmit */
#define         TIOCM_SR        0020            /* secondary receive */
#define         TIOCM_CTS       0040            /* clear to send */
#define         TIOCM_CAR       0100            /* carrier detect */
#define         TIOCM_RNG       0200            /* ring */
#define         TIOCM_DSR       0400            /* data set ready */

But it *is* helpful to know that TIOCMSET/GET are explicitly listed as not
supported in 1.3.3 or earlier.  I don't mind loading 1.4, 'long as I know
it's going to work.  Thanks, guys.

Regards,

Michael Maciolek
